switch off the lights in the afternoon for 2 hours this will reduce algae. For new tank 8 to 9 hrs of lightning is ok and i dont no the white thing instead of using air stone you can use small submerged filter and use co2 when lights are on

the tank showed healthy growth with the star grass, cabomba sticks, amazon until last week

but recently, 90% of the star grass melted in 2 nights, cabomba sticks are turning black/brown. but their growth is fast.

amazon had the best growth, but recently, there are brown dots appear on the leaves and they get bigger and turn into holes in the leaves.

added dwarf grass which was covered in algae after 2 days of planting. the growth is fast and its spreading, but its colour has changed from bright green to yellow. also, there is no algae growth elsewhere in the tank.

all the plants respire very well.

the water in the tank turns yellowish/greenish 1 day after the water change. i do 50% water change every sunday.

what is so horribly wrong with the tank?

till last wednesday, the tank had healthy plants, clear water everything like my dream tank. thursday, the plants started becoming brown, friday water started turning wellow, saturday 50% plants were ruined, sunday water was green and all the things mentioned above happened.

did a 75% water change yesterday. the water was clear as before. saw the tank today morning, it was milky. afternoon it started becoming yellowish.
